Hey actually that ain’t a half bad idea. I’m a barbarian, tipping out spikes to stab people with sounds like something I’d totally do.
Assuming the enemy is unaware and that the group intends to more or less pounce with the element of surprise, is it reasonable to assume those jumping the gap - as they are coordinating it to do so - receive that as their surprise round and combat proceeds with them on the other side from there, @Hekazu?
